NEMIX RAM DDR5 4800 288GB (6x48GB) CL40 1.1V 2Rx8 ECC RDIMM Supermicro H13SSL-N memory upgrade

288GB DDR5 ECC RDIMM kit for Supermicro H13SSL-N

This 288GB kit contains six 48GB DDR5 4800 modules built to the exact rank, voltage and timing the Supermicro H13SSL-N memory controller expects. Registered ECC architecture with 2Rx8 organisation and CL40 latency ensures the board recognises full capacity at rated speed. It is designed for servers that require registered DIMMs and error-correcting memory. Systems needing unbuffered UDIMMs or non-ECC modules cannot use this kit.

Sustained load behaviour with registered ECC

Registered buffering offloads the memory controller so all six slots run fully populated at DDR5 4800 without signal degradation during continuous operation. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots under heavy, long-running workloads. The 1.1V operating voltage keeps power draw stable across extended duty cycles. Workloads that exceed the 288GB total capacity will still require additional memory channels or a different platform.

Upgrade path from smaller registered DDR5 kits

This kit replaces lower-capacity registered DDR5 RDIMM sets when the Supermicro H13SSL-N needs its maximum supported memory population. The jump is worth it when applications demand the full 288GB address space and the board's population rules allow six 2Rx8 modules at 4800 MT/s. Installations limited to fewer DIMM slots or lower per-slot capacity limits will not benefit from this configuration.
